Analysis of the three characteristics of sanitary pipe fittings

Analysis of the three characteristics of sanitary pipe fittings 1. Weldability, sanitary pipe fittings are used for different purposes, and their welding performance is also different. Some tableware does not require welding performance, including some pot companies. However, most products require good welding performance of raw materials, such as Class II tableware, thermos cups, steel pipes, water heaters, and water dispensers. 2. Corrosion resistance, many stainless steel sanitary pipe fittings have good corrosion resistance in food, such as first and second class tableware, kitchen utensils, water heaters, drinking fountains, etc. There are many foreign merchants regarding the corrosion resistance of sanitary pipe fittings Also tested: heated with NACL water solution to boiling, poured out the solution for a period of time, sucked clean and dried, weighed weight loss, to determine the degree of corrosion (note: when the product is polished, because the abrasive cloth or sandpaper contains Fe ingredients, Will cause rust spots on the surface during testing). 3. Polishing performance (BQ quality) Sanitary pipe fittings polishing performance (BQ quality). At present, many industries need to polish stainless steel sanitary pipe fittings. Only a few products such as water heaters and water dispenser inner tanks do not require polishing. It is very important in terms of raw material requirements. Factors affecting the polishing performance of sanitary pipe fittings: ① Surface defects of raw materials. Such as scratches, pitting, pickling, etc. ②Material problems of sanitary pipe fittings. If the hardness is too low, it is not easy to polish during polishing (BQ performance is not good), and if the hardness is too low, orange peel will easily appear on the surface during deep drawing, which will affect the BQ performance. BQ with high hardness is relatively good. ③After deep-drawn products, small black spots and RIDGING will appear on the surface of the area where the amount of deformation is extremely large, which will affect the BQ performance
